@brief Get entity subscriber. @ingroup entity @component entity_relations

If the reader is for a built-in topic, this returns the participant’s built-in subscriber.

@returns A valid subscriber handle or an error code.

@retval >0 A valid subscriber handle. @retval DDS_RETCODE_ERROR An internal error has occurred. @retval DDS_RETCODE_ILLEGAL_OPERATION The operation is invoked on an inappropriate object. @retval DDS_RETCODE_ALREADY_DELETED The entity has already been deleted.
